Question

Which of the following mark the left edge of one-way roads and separate opposing lanes of traffic on two-way roads?

1) Solid white lines
2) Solid yellow lines
3) Dashed yellow lines
4) Dashed white lines

Answer 1

Solid yellow lines mark the left edge of one-way roads and separate opposing traffic lanes on two-way roads, whereas solid white lines and dashed white lines are for lanes of traffic moving in the same direction.

Step-by-step explanation:

Traffic Lane Markings: Lane markings are usually broken lines white in colour dividing the road into lanes, each of 3.5 mtrs. Border or Edge Lines: These are drawn at the road shoulders with solid lines usually in white or yellow colours. The solid yellow lines are typically used to mark the left edge of one-way roads and to separate opposing lanes of traffic on two-way roads. On a two-way road, these lines indicate that you are not allowed to cross over or pass.

In contrast, dashed yellow lines may indicate that passing is permitted when safe, depending on the direction of the flow of traffic and your position on the road. Solid white lines are usually used to mark the right edge of the roadway and denote lanes of traffic moving in the same direction, while dashed white lines separate lanes of traffic moving in the same direction where changing lanes is allowed.
